Ciliated hepatic foregut cyst (CHFC) is a rare lesion which originates from detached hepatic diverticulum or from detachment and migration of buds from the esophageal and bronchial regions of the foregut which subsequently get entrapped by the liver during the early embryonic development of the foregut. CHFCs are mostly seen in adults and are rarely reported in children, with only about 10 cases reported in this age group. Hereby, we present two cases of CHFC in two 3.5-year-old boys; one of them had cystic lesion at medial segment of left lobe of liver (common site), and in the other one it was located at right lobe of liver (less common site). Histologically, both cysts had four layers composed of inner ciliated, pseudostratified, columnar epithelium; subepithelial connective tissue; smooth muscle layer; and an outer fibrous layer.
纤毛肝前肠囊肿（CHFC）是一种罕见的病变，它起源于分离的肝憩室，或源于前肠食管和支气管区域芽的分离与迁移，这些芽在胚胎早期前肠发育过程中随后被肝脏包绕。CHFC多见于成年人，儿童中很少报道，该年龄组仅有约10例报告。在此，我们报告两例3.5岁男孩的CHFC；其中一例在肝左叶内侧段有囊性病变（常见部位），另一例位于肝右叶（较少见部位）。组织学上，两个囊肿均有四层结构，由内向外依次为纤毛假复层柱状上皮、上皮下结缔组织、平滑肌层和外层纤维层。
